3 Claims.

This invention. relates to harvester trailers for bunching straw 'andchai.

An object of. the invention isto provide a buncher that will neatly pilethe bunches and at the Sametime produce larger bunches than othermachines noiw commonly in use,

Another object is to provide a machine of this type that. will bepositive in operation and having all of its mechanism driven by its owntraction alone, no power, other than the pulling being furnished by theleading vehicle.

Another object is `the provision of a machine that will dumpithe bunchesat the pleasure of the driver and dump them so that they will be in'compact bunches and not spread along the path of the vehicle.

Another 'object is the elemination of the usual cumbersome hood found onthe conventional bunchers.

StillA anDtherobject 'is the provision of such a'machine that at alltimes and under all conditions willremain close to the ground, thusproviding a maximum capacity thereof.

And a lfurther object is to provide a` trailer buncher of extremelysimple design and one that maybe manufactured cheaply and operated by amost inexperienced hand.

These `and other objects will become apparent by a reading of thespeciiication taken in connection `fwith the accompanying drawings, yinwhich:

Figure 1 'is a topplan view of the machine as it would vappear ready'foroperation,

Figure 2 is a `side elevation illustrating the dumping mechanism inoperative position,

Figure 3 is van elevational View, partly in section; taken on the line 33 of Fig. 1.

Figure 4 is a side elevation, similar to Fig. 2, illustrating the partsin inoperative position, with outer part-s removed ior clearness,

Figure 5 illustrates the details for meshing andvv taken 'on the line .2justablemeansgof Fig; 10, mits relation to other parte Figure 12showsthe adjustment onV the right hand side for maintainingthe chains, vatproper tension and Figure 13 is the 'adjustment on the left hand sidefor thesame purpose as that of Fig; 12.

Referring howto the drawings; ,thenumeral l 5 indicates the buncher lorV-windrower generally which is provided'with th'e upper longitudinalframe members V164 and 'l1 .and similar lower' frame members i8 andA I9.At theforwardend of :the frame is arranged .any conventional 'type ofhitching means such as the clevis 20."

Located at the Arear ofthe frame is a shaft 2l which is journaled ineach`side 'thereof fand has 'traction wheels 22 and l23 4rigidly"mounted onvthe ends thereof; Similar, orany other desirable type wheels arepositioned at the .front but are not shown inthe drawings;

Conventional side boards 24 are located on each side and are supported'by` the uprights 25. Atone endofa rockablesaft 2| fand" on the outside'of the shaft :journal 26, is loosely mounted a gear `wheel 2`T"fromwhich extendsany -desirable number 'of "studsl 28 vand`29 which protrudethrough the curved "slots '30 and 3| in the wheel The outer ends/ofthelstuds have attached 22. thereto one end of the springs 32"'and 33 theotherends of the "springs beingjconnected 'to' the 'pins 34 and 3`5andthese 'pinsare rigidwith' and :which will move saidchains when they are'rotated. The shaft SilisV also jcurnaled` in the frame of the-machinebut is permitted Vslight` rocking or backward andforward `movement on"the driving "side by means of the roller bearing 44, Fig. 7, beingarrangedin the lslot 45 of 'the frame.

Theopposite end 'ci the shaft Vil!! `is permitted na slight Wobblin'gmovement.

At the driving endof the shaft 39 `'there is rigidly held a "gear Vwheelnlil so that 'when the yoke 115; which is arranged overthe rollerv'bearing 44, is

moved forwardly (see-Operation) the gears 49 and 2l will mesh. Inorderto ycontrol this movement "there," is :pivotedly :fastened to 'the -yoke4E y an 'arm 50,` its .orward end beingpivotedly attached'ntermediatethe endsof an upright arm" 'Iiiestay bolts 41 and siirm'ly retain` theupper and lowerirame 'members lli and 'FB in close =relationship 'totheslotted member 48.

I as indicated at 52. At the upper end of the arm 5i may be arranged anyconventional means, such as the rope 53 leading up to the front vehicle.The arm 5| is pivoted to the frame as indicated at 54.

The parts from the yoke 46 to and includingr the rope 53 are normallyheld in their rearward positions by means of the action of the spring55, its forward end being attached to the pivot 52 and its rearward endto the clip 55, the clip -being rigidly held on the lower frame memberI8 and also acts as a guide for the rod 51.

The rod 51 is also attached to the yoke 46 and at its forward end isadjustably connected to a cross-shaft 58 having an opening therethroughfor reception of an adjusting bolt 59 which will extend into the openend 60 of the rod 51 and be locked at the desired position by means ofthe double lock nuts 5I, the forward end of the bolt 59 being lockedsecurely by the nut 62. The shaft retaining member 53 is slotted, asshown at 64, thereby permitting forward movement of the shaft 5 8.

Loosely mounted on the shaft 58 are two sprocket wheels 85 and 55 overwhich the chains 42 and 43 play. The opposite end of the shaft 58 isjournaled in a frame member 61 and may be held therein by means ofth'eadjusting screw E8 which extends through the opening 69 at this endof the shaft and is held therein by the lock nuts 1U. The forward end ofthe bolt 68 rests in the angle member 1I and is held therein by means ofthe nut 12. This adjustment is left sufciently loose in order to permitof a slight wobbling movement thereof.

Connecting the two chains 42 and 43 are slats 13 of sufficientthickness, or angle irons, if preferable, which are arranged torearwardly move the deposited straw and chaff and to discharge, from therear of the machine, one bundle at a time.

The flooring may be of any preferred material such as the boards 14 andhas the cross members 15 arranged thereunder for additional support.

Any suitable means, not shown, may be located under the iiooring tomaintain the chains 42 and 43 and slats 13 .close to the ooring, therebyeliminating any undue sagging.

Referring particularly to Figs. and l1, there is illustrated anautomatic and adjustable means,

for varied and intermittent movement of thel conveyor. It consists of acrank-arm 19 pivoted at 88 to the frame member I9, its lower crank 8|being actuated by a cam 82 and the cam being keyed or otherwise rigidlyheld to the shaft 2l. The upper crank 83 Aof the crank armis pivoted at84 to the forward end of the pawl and has its rearward end restingbetween two teeth of the ratchet wheel 85 whichis rigidly mounted on theshaft 39.

A lock member 88, when actuated by a spring 89 will prevent reverserotation of the ratchet wheel. Attached to the upper crank 83 is one endof a spring 9U while its other end is attached at 9| to the frame memberi9. With-this arrangement the spring 90 will return the crank to itsnormal position, a-fterthe same has been actuated. A set screw means 81,mounted on beam I1, limits the rocking movement of the crankV 19 inresponse to the action of spring 90.

Operation when the rope 53 is pulled forward this action likewise movesthe arms 5I and50 forward, likewise the yoke 46 and the last mentionedelementwill bear against the roller bearing 44 thereby forwardly movingthe shaft 39, the slot 45 in the frame permitting of such movement,which continues until the gears 49 and 21 are meshed. As the rearwardends of the slots 30 and 3l are catching up with the studs 28 and 29 thegears will have ample time to completely mesh without any clashingthereof and when the rearward ends of the slots do catch up with thestuds the parts will be in the positions illustrated in Fig. 2. At thispoint positive action will take place between the gears 21 and 49,thereby rotating the gear 49 in a counterclockwise direction which, inturn, rotates the shaft 39 and the sprocket wheels 40 and 4l thereon,thus moving the upper side of the conveyor rearwardly. When the rope 53is released action of the spring 55 will return all parts to theirinoperative positions.

Normally the forward movement of the shaft 39 would allow of slack inthe chains 42 and 43 with danger of fouling said chains on the sprocketsor otherwise, but, such slack is 4taken up by means of the forwardmovement of the rod 51 which also is attached to the yoke 4B, suchaction pressing the forward shaft 58 an 'equal distance to the similarmovement of the rearwardl action will take place as that on the drivingside,

only to a lesser degree. The degree of rotation of the ratchet wheel maybe determined 'by means of the adjusting screw 81. The results of thisportion of the mechanism are particularly desirable when the conveyorshouldbe moved only a comparatively short distance.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a device of the class described, a gear wheel'arranged to rotatewith a traction wheel, a second gear wheel spaced away from and behindsaid rotating gear wheel, said second gear wheel being rigidly arrangedon an end of a rotatable and rockable shaft, a means to rock said shaftto cause meshing action of said second gear wheel with said rotatinggear wheel, said shaft having 2.
